What are the breeding techniques of climbing sand worms?

Sand crawler is a rare edible and medicinal insect, which has many consumer groups in Yunnan, Sichuan and other provinces of China. And with the decrease of wild sand crawlers, the price of sand crawlers is rising, and more and more people raise sand crawlers. Next, let's take a look at the breeding techniques of sand worms.

I. Culture facilities

1. Aquaculture pond: the aquaculture pond is 2 meters by 5 meters cement pool, the pond depth is 1 meter, the bottom is covered with river sand and flat pebbles, the bottom is equipped with a row of water pipes, the water depth is about 0.5 meters. Fill a corner of the pond with river sand and pebbles to form a slope. The slope is 45 degrees. The height is 1 meter, and the bottom area should not exceed 1/4 of the pool bottom.

Sheltering net: the sheltering net is 2m * 5m, with a height of 1m. The steel pipe frame is fixed on the cement pool, and then the sewn worm net is set on it, and the import and export is generally sewn with a zipper.

two。 Aeration machine: each pond is equipped with an aerator to keep the dissolved oxygen in the pool water above 6 mg / L for circulating water culture. The feeding and habitat environment is from July to September. During the period of pupation and Eclosion of sand worms, it is necessary to plant some flowers and small shrubs in the culture pond to provide insects for tooth flies to be put into foam boxes.

3. Seedling transport: the use of foam box oxygenated transport, can use aircraft air transport, automobile, train land transport and ship water transport and other means of transport, the damage to seedlings is light, and the survival rate of transportation is high.

Aquaculture management

1. Temperature: before the seedlings are transported back into the pond, the water temperature and salinity should be adjusted so that the temperature difference is less than 2 ℃ and the salinity difference is less than 5%. If the sand-climbing insects of all ages are put into the culture pond, the sand-climbing insects of the younger age should be reared separately so as to avoid being eaten by the sand-climbing insects of the older age.

two。 Culture density: there is a close relationship between sand-climbing insects and water environment, and the living environment requires high requirements, such as water quality, temperature, humidity, oxygen content, food and light, etc. the stocking density of seedlings is generally 50-100 per square meter. In order to promote the growth of insect body, it is necessary to select and separate culture in time according to the size of insect body in the process of culture.

3. Water quality management: the cultivation of sand worms belongs to flat culture, the water level does not need to be too high, generally maintain a water depth of 40-60 cm. In artificial culture production, river shrimp, yellow powder worm and fish bait are mainly used as bait. The feed should be of various types, fresh, pathogen-free and free of toxic and harmful substances.

4. Bait feeding: sand crawlers start to feed on their own at dusk, and their ability to find food on their own is the strongest at night, so when each feeding, it is necessary to evenly feed the yellow powder insects around the culture pond every evening. The number of yellow powder insects released every day is about 10% of the total number of sand crawlers.

5. Daily feeding: to ensure that the timing, fixed point. Purify the water quality, optimize the culture environment, and enhance the disease resistance to sand worms. Regularly remove Tenebrio Molitor residues and other perishable impurities every 2MUR 3 days. Regulate the pool water with quicklime water regularly or irregularly. Change the pool water regularly. In summer and autumn, it is usually cleaned every 2-3 days, and in winter and spring, it is usually cleaned once a week. In the early morning after feeding, after the sand worms have finished eating the remaining bait at the bottom of the pool, pull out the cold blocking and drainage of the drainage pipe, and wrap the drainage pipe at one end of the pool with a small mesh net in advance.

At present, sand crawlers have more consumer groups, and they are a household name delicacy in Sichuan, and they can be eaten in both large and small restaurants. The prospect of breeding is also considerable.
